What Is an M12 Lens?

An M12 lens, also known as a board lens, features a standard M12×0.5 thread mount and is commonly used in compact camera modules.

Key Characteristics:

• Small size and lightweight design
• Cost-effective for mass production
• Easy integration into embedded systems
• Wide range of focal lengths and angles

Typical Applications:

• Surveillance and CCTV systems
• Automotive cameras (rear view, ADAS)
• Smart home devices
• Robotics and AI vision
• Industrial inspection

Key Parameters of M12 Lenses

Understanding lens specifications is essential when comparing products from different manufacturers.

1. Focal Length

• Determines how wide or narrow the view is
• Common options:
  • 1.8mm (ultra-wide)
  • 2.8mm (wide-angle)
  • 3.6mm (standard)
  • 6mm (medium zoom)
  • 12mm (telephoto)

2. Field of View (FOV)

• Wide-angle lenses capture more area
• Narrow lenses focus on distant objects

3. Aperture (F Number)

• Controls light intake
• Lower F-number = better low-light performance

4. Sensor Compatibility

• Must match camera sensor size:
  • 1/4″
  • 1/3″
  • 1/2.5″

5. Distortion

• Wide lenses often have higher distortion
• Important for applications like machine vision

6. Optical Structure

• Number of glass/plastic elements
• Impacts clarity and durability
